public class FrenchGeocentricNTF2RGF
extends AbstractCoordinateOperation
implements GeocentricTransformation, GridBasedTransformation

French Geocentric interpolation is a transformation used at IGN-France to transform coordinates from the old local NTF system to the new ETRS-89 compatible RGF93.

It is a geocentric translation which parameters are interpolated on a geographic grid.
